Adding a section to a sidebar column

Hi,

For some reason, it’s not letting me add an inner section to the sidebar column of my blog.

Currently, I have one main section so I can have the blog heading span full width and within that I have an inner section split up into two, one for the blog content and the other for the sidebar content. I’d like to add another inner section to the sidebar column, is this not possible?

I need to add the inner section so I can house all the sidebar widgets and set it to sticky rather than have to set sticky rules on every one of the sidebar elements individually.

Thanks
